I. Introduction
Micro-projectors (referred to as micro-projections) can be described as small but complete, and with a series of products, Internet of Things, the projection industry in recent years has also set off a wave of intelligence. Intelligent micro-projection as a projector, can achieve a compact body, provide a wealth of features, make more affordable prices. But precisely because of its limited size, the previous micro-projection was either limited in display capability (poor performance) or it was too expensive to enter the sight of ordinary consumers.
With the development of technology and the increase of public demand for home projectors, there have been many companies that produce micro-investments. The company is such a company, from 2012 to Z2, to Z2, to Z3, then to Z3S, Extreme Technology has launched four generations of smart projection products before and after, and its market share has reached an astonishing 49%. %. In particular, the Z3S, from the original article of Zhang Aunt, opened, everyone praised Z3S continuously. The following figure shows the products of Zengmi Science and Technology. From left to right, they are Z1, Z2, Z3 and Z3S.
Now Miji Technology has launched their fifth generation products, which are the flagship series Z4X Z4X, the performance and portable balance Z4 Air and the ultimate portable mango. In particular, the flagship Z4X, innovative use of dual-channel LED design, brightness reached 2578 lumens, about 580-amp lumens, brightness can be described as a huge improvement. At the same time, the resolution of the Z4X is 1280x800, which can project a clear picture of about 120 inches at a distance of 2.7 meters. It is worth mentioning that the Z4X uses the world's top audio brand Harman Kardon and is personally tuned by its chief engineer Alan Michel. The sound quality is very good. In terms of hardware, the machine has a 4-core CPU, 2GB of memory, 16GB of flash memory, and the interface is equipped with HDMI, AV, fiber, USB3.0, Bluetooth 4.0, WIFI-5G, wired network, and 2.5-inch SATA hard disk interface.
Zilometer Z4X went online in Jingdong crowdfunding for 3 days, which exceeded the goal of 2 million yuan in crowdfunding. In the end, only one month later, with a total score of 11.22 million, Jingdong Crowdfunds received the perfect ending and became the first tens of millions of home entertainment products in the history of Jingdong crowdfunding.
Second, out of the box
Thanks to Zhang Aunt’s preference, I got this chance to be tested. Originally I thought this life was out of touch with the test channel. Why? Looking at my application success rate, I applied 51 times and failed 47 times. At the same time, all the articles on the public test were badly written. I thought that I had already been designated as the blacklist of Zhang Ama. I didn't expect that Aunt Zhang would still trust me so much and give such a valuable product to me for evaluation. My heart is really awful. I believe that even if I'm busy, I'm guaranteed to have a great relationship every day.
The first time I received SF sent "the value is up."
After unpacking, it was very unexpected that a 3D glasses was included
Pull out the product, wrapped in a thick layer of inflatable bags. It has to be said that the product is not known to be good or bad, but the packaging is really very careful. In this case, even if it encounters "violence express delivery", it will not break.
Take out the protagonist, very "Apple" Fan. A circle echoes the "black film" of the product.
On the side of the package, Rami Technology and Harman/Kardon were written, giving a product that the two companies co-produced.
The film was peeled off, and the way to open the lid was to pay tribute to "Apple." You can see a sponge on the top of the left box to protect the machine.
Z4X's host uses a high-strength engineering plastic as the fuselage, white body, with a vinyl-like top cover, very attractive.
Projection part of the machine, the left is a projection lamp, the middle part is both a heat vent, but also the sound of the exit, the right is the harman / kardon's logo. Slide-type switch design is very user-friendly, the dust cover and power switch combined into one, push the lens barrier, Z4X will start.
There is an episode in this place. It should be the cause of the engineering machine. The lens at the camera has obvious glitches. In fact, this place I consider for a long time in the end to write, because after all, is the engineering machine, the product is inevitably a bit small, I believe the official version should not appear this problem, write it easy for the company's reputation is not good. However, written in this place, on the one hand is taking into account to give manufacturers a reminder, this place should be improved in the treatment, I hope the formal product does not appear this problem. On the other hand, it is also the principle of "actually it is" that Damascus has always insisted.
The butt of the machine occupies more than half of the heat dissipation area. The right side is a cable interface, power interface, a USB3.0, a USB2.0, two HDMI interfaces, an AV interface, a headset interface, and a reset button.
Both the bottom and the top are "black film" designs that form the backdrop.
Unscrew the three screws, open the lid, there is a 2.5-inch slot, this is very good, and the Thunder itself can be downloaded and matched with the machine itself, to reach the purpose of using broadband when not at home.
In the hands of the company, there was an idle Shadow Warrior SSD, which was bought by more than 300 oceans. It was later discontinued and production was suspended. Please ignore the stains on the SSD. At that time, tape directly to the desktop chassis and remove it. The place marked in blue is where the screws are installed and the hard disk is fixed.
The machine comes with a fixed hard drive screws, a total of four, two use, two spare.
Put the machine aside and look at the remaining accessories.
The first is this manual. The design is very simple. It is a card. Although the description of the feeling is short, many problems are not explained, for example, how to remove the hard disk after the lid is added.
At the bottom, two boxes were placed and remote controls and power cords were installed inside.
The machine's box is also better, surrounded by a buffer layer. It can be seen that, on the packaging, Kamitsu Technology really did not work hard.
The remote control is similar to the remote control of the millet box, but it is smaller and lighter than the remote control of the millet box. The power adapter is similar to the laptop's power adapter.
In particular, the power adapter is used by HuntKey.
Finally came a family portrait.
Third, the use of experience
After starting up, it automatically enters the meter launch page.
The startup page is not yet visible, but the entry into the second page becomes very clear and really exceeds expectations. In the original impression, the projector was ambiguous. I did not expect that the photo projected onto an ordinary wall would be so clear.
The first time you need to adapt the remote control and projector. There is a problem with this place. At the beginning, my remote control can be adapted to the projector according to the instructions. However, it cannot be used. It cannot be used after one afternoon. Afterwards, he called the customer service. After half an hour of communication, he confirmed that it was a problem with the remote control. The customer service immediately decided to send a remote control over and sent him a favor for the service.
Then start focusing settings, log in to the meter account (can be linked to WeChat), gestures using tutorials, scan the code to download the meter assistant.
After entering the main page is very simple, the left side can select the input source, you can choose an external U disk, built-in storage space, two HDMI input, or an AV interface input. Can be used as a television only, but also as a display.
The box function of the projector is divided into four columns: movies, music, games, and applications. The logic is very clear.
On the right side of the homepage, because the Mango TV card is currently being distributed, it is still unfinished. Therefore, most videos cannot be seen, such as “Spend One Thousand Bone.â€
The second level menus for movies, music, games, and applications, and the second level menu for personal feeling music have the highest facial expression value.
Some games can use game controllers and they are marked separately. Personally, this is a good feeling. Because there is no gamepad in the hand, this will not be evaluated.
However, some games can be played with a remote controller, such as the following parkour game.
Music player interface, this black film is similar to the machine's design language, is a square, a circle.
Video playback screen, the screen effect is great, far better than expected.
Try a movie, er, or wait for the mango video card to be sent.
Fourth, color testing
The main reason I didn't want to write this one is that I currently have not even a decent camera. I can't shoot the effect I want. I just graduated from my job and I haven’t got paid for the first month. Water SLR pit). Another very important reason is that I don't like running points very much. I always feel that there is no necessary connection between limit testing and experience.
Then, first on the Zhangan Bunny's running sub-map for everyone to look at, 21473's running points, should be good, running points and millet 2 is comparable, this score can ensure smooth viewing of video and play games.
The color transition test shows that the uniformity is good.
Display of solid color pictures
High-definition image proofs can be seen clearly and can be described as "TV".
Because I use a mobile phone to take pictures, the photos taken can not completely reflect the actual viewing experience, I feel very embarrassed to everyone in this regard. Here I would like to say is that if you have never used a projector before the value of friends, then the brightness of this projection will definitely not let everyone down, it should be said that it is beyond expectations.
Fifth, sound quality feel
After a period of use, I feel that the Z4X sound quality optimization is very good, especially the middle and high pitch, in this regard I think that is not as much measured in a small room.
Cai Qin's "River" and "California Hotel"
Because there is no professional recording equipment, just as good as possible to express the sound quality, so the actual listening to music feels much better than this video.
In short, after Z4X, the biggest surprise is the brightness and sharpness of its projection, followed by its sound. The haman/kardon custom sound system used does give people a feeling of no money. (Although I did not spend money)
Six, 3D glasses, remote control, rice assistant
For the remote control, a logo on the front of the meter is printed.
Specifically, talk about the left and right focus keys below the remote control's power button. Personally think that the Z4X has a big drawback is that it can only focus through the remote control. This leads to the fact that if the remote control is bad or cannot be matched with the machine, it will not be able to focus. The Z4X cannot be used. Only a relatively clear picture can be formed by moving the distance of the machine, and then insert the mouse. Do not know, generally to call the customer service phone will know that the polar meter Z4X can be operated by the mouse) to initialize, connect to wifi, and then use the mobile phone to download the meter assistant, when the pole meter assistant can not focus, and finally Focus can only be adjusted with the remote control. This leads to a problem. If the remote control is not usable, focus cannot be achieved. The left and right arrows refer to the focus button.
I personally think that the best solution to this problem is to add a focus dial to the camera. When the machine is initialized, it can adjust the focus by adjusting the dial, so that you can bypass the remote control. Even if you forget to bring the remote control for business trips, it doesn't matter. There will be no situation in which focusing will not occur. As shown in the figure, it will be much easier to add a focus dial as shown below.
The reverse side of the remote control, like the millet box, uses a button battery.
Unexpectedly, this time, a number of 3D glasses were added to the product. This product itself did not exist in the product parameters.
Glasses are 3D active shutter glasses.
There is a pair of glasses, a pair of glasses, a bag with glasses, and a data cable. Huh? Why do you have a data line?
Look at the glasses body. To be honest, workmanship is very good and exceeds expectations.
Above the glasses. The button on the left is when watching a movie. When the button is clicked, the glasses start to power on. After viewing the 3D movie composition, there will be a very obvious 3D effect. The right side is the charging socket. After all, it is active and needs to be charged.
Extreme-Tech has specially prepared a meter assistant for the mobile phone, which can be operated by the mobile phone terminal Z4X.
Access to the meter assistant first selects the device, and a mobile phone should be able to control multiple meters.
After selecting the device, you can use the remote control to control the Z4X. There is one more voice control than the remote control that comes with the machine (it has been tried many times without success), and it has less focusing than the built-in remote control (important).
Remote control expansion options. Including the input, touchpad, keypad, a key 3D, screenshots, mute, shutdown and other options.
Input options, you should know the value of the TV box you use. The TV box search program is the same as the KTV song. It is the first letter of each word of the name. Sometimes it costs brain cells. The input function can directly use the mobile phone input method to search for the program and send it to the Z4X.
The usefulness of the touchpad is almost the same as that of a laptop touchpad.
Because the Z4X comes with 16GB of flash memory, it can support screenshots.
In addition to the remote control, the Mi Mi Assistant also has some extended functions.
For example, with the same screen function, the projector screen can be transmitted to the mobile phone in real time. This is the use of mobile phones to control the Z4X Zimmer can achieve WYSIWYG.
Mobile phone resources and Mimi Cloud Screensaver can transfer photos from the phone to the projector in real time.
Seventh, last review
From Z3S to Z4X, many people expect their projection resolution to be upgraded from Z3S 720P to 1080P. After all, the level of Z3S is already very high, why does the polar meter not upgrade its resolution, and the trend is to launch 1080P? Micro-projection? I also had this question when I didn't receive the test products. Now I think I can answer this question. First of all, projection differs from the display industry. The increase in cost from 720P to 1080P is much greater than the increase from 720P to 1080P in the display industry. At the same time, the distance from the projector is generally greater than the distance from the monitor, even if one is used to viewing the 1080P monitor. Let him see the 720P projector will not feel clear enough. The overall cost and the specific use of the scene, the introduction of a high price in the early stage but not practical 1080P micro-projection products is not wise. Secondly, although the Z3S is very good in all respects, the 720P has a fierce market competition. After the Z3S was launched for almost a year, the Extreme Meter launched the Z4X, which is extremely outstanding in all aspects, naturally occupying more micro. Market.
It has been 2 weeks since the beginning of product-to-hand writing of test articles. On the one hand, it is due to the busyness of starting work recently. We can only rely on getting home from work and studying early in the morning for a period of time. On the other hand, I just don’t want to write too early. I always feel that a product can only be used after it has been used for enough time to discover its excellent places and shortcomings.
The following highlights my true feelings during this time.
Advantages:
During the period of using the Z4X, I deeply feel that this micro-projection is a product of Dacheng. From the unique appearance, to the excellent picture, to the ultimate sound, to the design of the final product details (GMUI system, Thunder remote download, etc.)
1. The Z4X pole adopts an innovative dual-optical path design. The brightness of the Z4X will be raised to 580 ampere lumens at a price of up to 3,000 yuan. Even during the day, it can be used normally and its effect is not bad. If there is no sunlight at night, only a white wall is needed to achieve the same effect as a TV set. I think this is the reason why R&D dares to name it super-screenless TV.
2, Harman/kardon custom audio system, the sound quality did not have to say, especially considering the three-dimensional size and weight of the Z4X, can put such a good effect of the sound into the portable meter Z4X inside To ensure excellent sound quality, here's a big praise. Therefore, I think if you want an external speaker, please connect 5.1, if the external sound is less than a thousand dollars, or do not toss.
3. The appearance of the unique “Vinyl Recorder†is absolutely high enough in the projector field. Under the black and white, the shape of "Tianyuan" also makes it not appear abruptly in any place in the home.
4, comes with the quad-core CPU + 2G storage, unique GMUI system, so that the use of ultra-sensitive rice Z4X reaction, no Caton feeling. Some people may think that it is meaningful to have a TV box to configure. In fact, when more and more video apps and games are installed in TV boxes, the most basic requirement of "non-catching" can filter out many TV boxes. Moreover, the Z4X is not only a TV box with a few hundred dollars. If the Caterpillar problem is caused by the configuration later, it can't be said to change. It is almost 3000 RMB.
Of course, any product can not be all advantages. As the flagship intelligent micro-projection in the fifth-generation products of Mimics, the Extreme Z4X will still have some insufficiencies in all aspects of innovation. . Some of these deficiencies are due to the engineering machine, and some are because they do not take into account actual use scenarios.
1, the pole Z4X comes with a 2.5-inch internal hard disk interface and 2 USB ports (a USB2.0, a USB3.0). I don't know if it was because of the engineering machine, but when I connected the hard disk to the Z4X, USB2.0 failed. However, if you take the 2.5-inch hard drive, USB 2.0 is easy to use. I guess this should be the reason for the lack of power supply. I hope the manufacturers can take care that the official version does not have this problem. Because the Pozi Z4X can be controlled by a mouse, both USB ports are important.
2. Although the Z4X uses a Harman/Kardon sound system, it has excellent sound quality, but it cannot be used as an independent Bluetooth stereo. I learned from the disassembling picture of the Z4X. The Z4X comes with a Bluetooth 4.0 module. If you can not add a projector and use it as a Bluetooth stereo, I believe that more people will like it.
3, projector's focusing function is essential, polar meters Z4X focus can only be used by the remote control, in the use of a change of scene, if the remote control fails or the remote control does not carry, this time either through the mouse The focus control function cannot be achieved by controlling the machine or using the meter assistant. Focus adjustment is only performed by resetting the factory settings for initialization, which is inconvenient. It is hoped that the factory can add the option of focusing to the Mi Mi helper when updating the Mi Mi helper at a later stage.
4. When listening to music with Z4X, if you want to jump out and find out if you have a good-looking movie or TV show or if you have a fun application game, you must completely jump out of the music application. That means you must completely turn off the music, and you cannot listen to it. Music finds TV shows, movies, games, etc. I hope that when the manufacturer upgrades the system at a later stage, the function of finding other contents while listening to music can be added.
Before I touched the smart micro-projection, how do I think a projector might replace the TV? But after I really touched the Z4X, I was shocked by it. A projector product can achieve less than 3,000 price, picture and sound can reach the level of television, although there are some small enough shortcomings, but after all, not on the hardware, I believe that the late system upgrade can be completely solve these problems. Many people on the Internet call it a "household artifact" because it has the effect of a television, but it is much easier to carry than a television. So here I would like to comment on this pole meter Z4X in one sentence:
Home with two suitable, picture quality bar å“’
Because the official version of Aunt Zhang's survey product was not on-line, the VIP card of Mango TV was not included. I thought it was gone, but later on, Aunt Zhang specifically called me and told me that because the official product was on-line, the manufacturer had reissued the VIP card of Mango TV, but it would take a week before I could send it to the deadline. Since I hadn't received it yet, I didn't write the contents of the VIP card for Mango TV here, but I still want to like the working principle of Mami and Zhang Aunt.
Finally, thank you once again for what is worth buying and knowing that you can submit such a valuable product to me for evaluation. The deficiencies of the article, please also a lot of correct me, thank you.
